What are the disadvantages of using Jira?

Jira’s flexibility and depth come with a steep learning curve and significant administrative overhead, as teams must master complex configurations and dedicate resources to ongoing maintenance. Large instances can suffer performance bottlenecks and require disruptive re-indexing, while licensing and add-on costs quickly escalate. 

Over-customization risks process fragmentation and upgrade headaches, and native reporting tools are limited without additional plugins or BI integrations. Finally, the crowded UI and integration complexity can hinder adoption and create data silos if not carefully managed.
